My invention relates to the improvements' in electric locomotives andthe objects of the improvement are to provide a locomotive of greatpower for operation at high speed on track with lig-ht rails, sli-arpcurves and heavy grades; to enable` such locomotive to operate withsafety and reliability on elecf tric current ol high tension so tfhatconcluetors ol comparatively small size may be used lo to 'convey thecurrent to it. Other objects willappear in the description.

I 4attain thesev objects by the mechanism illustrated in theaccompanying drawings, in which: fl

`Figure 1 is a side elevation partly in section and Fig. 2, an endelevation partly in sectionof alocomo-tive truck having two drivinglelements which may be operated that way or extended to contain three ormore of the driving units. Two or more oi these trucks may alsov becombined to' form a single locomotive. The four sec-A tions shown inFig. 1 are taken on Fig. 2 as indicated by the dotted lines as followsf5that part to the left ci a vertical line through the axle 11 at 1, 1,Fig. 2.; that part between a vertical line through the center oit thevaxle 11 and a vertical line through the longitudinal center ofy thetruck at 1A, 1A, "i" Fig. 2; that part between a vertical linethroughthe longitudinal center ol' the truck and a vertical line through the.center-fof axle 12 at 1B, 1B', Fig. 2, and that part to the right oli avertical line through the axle 12 'f at 1C, 1C, Fig. 2, all looking inthe direction indicated by the arrows.

The sainetype of construction is shown in two places in- F ig'. 8.

Similar reference` characters refer to' simlla-r parts throughout theseveral views.

Referring to Figs. 1 and 2, the main frame 13 or' the truck hasvertical' faces', one at each side or' each axle box for the receptionof the wearing shoes 14, held up inpla'ee by ,the cross bars 15. Theaxle boxes 16- with removable wearing brasses 17 and dust guards 18,each havey projecting outwardly and' upwardly from them on each side atan angle of about l5 degrees the two arms 19. These armsare mad-eI withflanges at their outer ends tolit angle bars 20, which extend across thelocomotive and conneet the ends of' they arms 19 of the two axle boxesof an axle by Ine-ans of rivets. Leaf springs 21, are mounted inl thetruck frame 13 and bear' on the tops of the axlel boxes 16 to springsupport the truck frame inthe usual way.

I will now describe the motors oney of which is mounted on axle 11 andone on axle 12. As these two motors are exactly alike I have used thelsame reference signs for them so `the description ol one will apply toboth. The armature parts consisting of the notched soit steel rings 22,the commutator bars 23, together with theusual windings, insulation' andbinding wires, are carried on the meta-l sleeve 24E. It will benotedthat the commutator bars 23 are built into the sleeve 2li instead ofbeing assembled in a separate casing as is' the usual practice. Theobject of this construction is to provide' bars olf large capacity inthe small space available because or the largeinternal diameter oi' thelsleevel 24. O11 the inner surtare ot the sleeve 2t is placed insulationtube 25, made ot material ot high heat and electric resisting quality.Fitted to the axle on which the armature is mounted are two long hubs QGprovided with a series ot tapered slots to receive the tapered centralflanges ot the. T shaped bars QT. rFliese bars are curved across the Theads to tit. the curvature ot the inside ot the insulatii'ni tube 25.lVhen the two hubs Qt are brought together the wedging action will causethe bars 2T to be pressed tightly against the insulation and Vt'orm anetl't-etive drivnrr means between the armature sleeve it and the axle.rlhe hubs are. held together bj; means of the tianges E28 and the boltsZtl.

The field Vtrame. ot the motor consists otl two assembled parts ill) and3l, arrzineed to be bolted together or a horizontal line running?Ythrough the center ot tl i axle b v means ot' the bolts 32., two at eachend. 'lhe 'framework of the upper trame il() ot the tield l'rameconsists olf the rectae'ular Vtrame. 2525 within which the rectangularshaped trame flis partly inrlosed. '.ihe trame lll is composed partly otmetal and partly ol' insulating material as shown by an enlarged sectiono'l one ot the corners in Fig. 3. The two pole pieces 35 which arecarried in the upper trame 30, each have brackets llo. one at each side,and brackets 25T. one aty each side. attached to them. The brackets 3G,each have llanges at their outer ends and are attached to the tame 323and the upper part of the trame 3l by means of cap screws. The brackets'3T each have flanges at their outer ends and are secured to the spacerpieces 3S, the lower part oi the trarne 3l and the outer lugs 39 bymeans ot through bolts. The framework ot the lower 'trame 3l ot thetield trame, consists ol: the rectangular trame 1l-(l, within which therectangular pan shaped trame #il is partly inclosed. The trame 4l iscomposed partly ot metal and partly ot insulating inaterial as shown byan enlareed section ot one olf the corners Fie'. Il. lihe two bolepieces ft2 which are carried in the lower trame 3l. each have bracketslf3 attached to them at one side and brackets il attached to them at theother side. These bracluits l' and il each have tlanges at their outerends and are attached to the trame l() and the lower part ot the trame`l-l by means ot cap screws. The two pole pieces l2 also each havebrackets l5 attached to them one at. each side, which have tlanges attheir ends and are secured to the spacer pieces lati. the upper part otthe trame `ll and the outer lues t7 by means ot through bolts. lt willbe noted that the outer lues 3). .l-'i' are for the purpose otcari-yin;Y the bolts 3Q which connect the two Ytrames 30. 3l tog'ether.

The pole pieces 35 and and their exciting coils lll and l) respectivelyare alike. so I will describe the construction and novel features ot onepole piece and exciting coil which will serve to describe all: Referringto the outline ot the right hand pole piece 42 ot the motor shown at therip-ht in Fig. l, it is made up ol` a number ott thin sott steel pieces5t), with a thick metal piece 5l. at each side secured together by longrivets :32 and a long rivet 53. l. Heter-ring to the outline shown in l"ij f. l, it. will be noted that starting at the lower pole where themetal is tapered and curved to Vt'orm the pole tace, the body ot themetal runs in a straight horizontal line ot a uniform width tor aconsiderable distance then turns to an angfle ot approximately 't5degrees and runs some distance ol a unitorm width which is the samewidth the horizontal portion, then curves tor a distance ot:approximately 90 degrees through which it maintains a uni- Vtorni widthwhich width is the same as the horizontal portion and the anglingportion then widens to the second pole At'ace which is approxin'iatelythe same width as the ti rst ment ioued pole tace and has the samecurvature. lt will be noted that this novel torni ot tield core providesa very short magnetic path requiring small excitingl- (,'apacity andthat it enables an eight pole motor ol' ligtht weight to be constructedin which thc diameter oti the armature can be approximately the same asthe distanov across its lieldy trame in one direction and in w nich thedimension across the. tield Atrame in the opposite direction is veryshort. The dimension ot the motor in the direction last. mentioned 'forthe tield traine is enabled to be still turther reduced by the novelconstruction ol the tield coils. Referring to the tield coils L19, oneshown in sectional outline on the pole piece ft2 that was describedabove, and the other in l'ull outline on the. opposite pole piece l2,Fig. l7 `it will be noted that the winding' which tills the spacebetween the pole taces spr ads out `tan like. which. owing,- to thecurved shape ot the pole pieci.` lan be done without lengtheningr thewinding to an appreciable extent. it any. thus toi-mini: a coil withoutside outline ot a triangle.

The rectangular trames 38. Figs. l and 2, are each provided with 'tourstud bolts 5l. and are secured to two ot the angle. bars 2t). throughinsulation The stud bolts .lare adjustable vertically and can be lockedin the position desired by means ot the nuts and 57 which have. suitablewashers between each of them and the insulation lt. will be noted thatby adiustment ot the stud bolts 5l the entire field trame can beadjusted vertically so as to compensate for the wear of the axle boxes1T. To facilitate this being` done quickly and accurately. I haveprovided a gauge 5S, Figs. fi and This lle consists ot the itwo pieces59 and 60 pivoted together by the-rivet 61; The piece 59 has a latch 62on rivet x63 and a projection ,64. This gauge is made of such dimensionsthat when the -notched portion of theprojection 64 is resting on the topsurface of the part 83 of the motor frame at one side of the motor, thelower points of the pieces 59 and 6() will bea-r on the underside of theinside end of the hub of the driving wheel next to that side of themotor. It it is found that there has been wear so as vto bring the upperpole faces ofthe motor too lnear kthe armature, the nuts 57 and 56 areturned to correct the matter. The use of two of these gauges, one ateach side of a motor, iis desirable.

Referring to Figs. 6, 7, 8, 9 and 10, which illustrate a locomotivehaving a number of trucks provided with motorsvlike that describedabove, Figs. 6 and 7 are side and end elevations respectively, on asmall scale, to showthe arrangement iu full of the trucks, thevmechanism for harnessing them together and the single car body used.Figs. 8, 9 and 10, on al larger scale illustrate some of the novelrparts more clearly.

The truck frames 65 each correspond with truc-k'frame 13 Figs. 1 and 2and in addition have ribs66 at the sides and projections 67 at each sideconnected together by a ribbed 'plate 68, the ribs =69 of which arecurved at the center to `form-a vertical bearing. The truck frames 65'each have two braking mechanisms, one at each side, not shown with thetruck These braking mechanismsare independent in their action exceptthat the compressed air with which to actuate them -is `i-ntel'id'ed-'to'be' supplied tl'irough connecting pipes so they willoper# ateysimultaneously. These braking mechanisms are'alike so lwill describe`one which will apply to all. The cylinder 7 O,-hasthe piston 71 onwhich the 'compressed air is intended to Vact Ion one side. Helicalconipressioii springs 72are disposed in the cylinder with one 'en'd 'offeachspri-ng engaging thelopposifte side off t-he'pist'on, t'heother endof 'each of the springs 'having engagement with flanges 7 3 attached tothe cylinder.'

ymain frame l"65. Fastened" to ithe upper Harige 73 of the cylinder 70is a yrope v81, as shown Pto the right in Fig. 8. This rope passesaround the pulley 74 on piston 7l, then yorrtwa'round the pulley 7 9 oitthe nearest arm 178, then back''around lpulley 580, 'then around pulleyl79 ofthe next arm 78 then back .arlound the pulley 80', sthengoutmzaround the pulley 579 of the :tarthest'a-rm 78 and back =to thefastening 82 on the main frame 65. This last is shown to the lett infFig. 8. Vhen the compressed yair is in the cylinder .70 the brakes arereleased. When the air is let out of the cylinder the Abrakes are set bythe springs 72 pressing the piston 7l back in :the cylinder and pullingon the rope 81; A chain may rope 81 if desired.

Referring to the mechanism for `:harnessing a number oit trucksltogether to 4liorm `a locomotive like .that shown in Figs. 6 and 7, itwill be noted that there lare eight truck framesy 65 which are coupledtogether i-n :four pairs, eachA pair by a `frame 83 which .consists oi aribbed plate 84 from which two pairs o the arms 85 extend in oppositedirections and are .connected across at their outer ends by 'the hollowround portions 86. The ribs 87 fof the ribbed `plate 84C :are curved atthe center of the plate to form a vertical bearing. `Ars the ribbedplate 68 `Fig. A10, is exactly lilke` ribbed plate 84:, -for the portionshown, 'that view Will serve yto illustrate it, the understanding beingthat lrib 87 is the `sameas rib 69./ Each one of the two round porbeused .in place of athe tions `86 of the frames 83, arepivoted for vtheir full length Aloetween the 'arms 85 in fa frame 88 whichhas journalstuds '89extending from it at the cen-ter to fit in :bearings in thetrough like frame 90 wliieh has projections at the center in which thebearings are 4'formed and which are curved on the outside lto tit insidethe ycurved ribs 69 on the frame 68 to vform a vertical bearing. It

will be seen that by the mechanism just de-v scribed the truck 'frames=65 are coupled together in pairs 'at a point located :centrally betweenthem by two universali joints which permit independent movement oi' eachtruck in all directions except as to the 'distance between the centers.Connection 'between the frame 88 of one pair of Ktrucks r65 and theframe 834 'of another pair of trucks lis lmade by the r'a'me9l, whichconsists of Athe truck bolster 92, to which fat each end, the 'two `bars.93 are attached.

`These bars are'connected together at each en'd by the round 'hollowmembers '94 each oi'l which has a bearing for nearly its -en- 4tire'length between the bars 93 in a frame 'which has journal studs 96 atits center corresponding `in shape to the journal st-uds 89 Fig. 10.This frame '95 is carried in a f trough like iframe 97`wliichat itscenter is 'like the frame 90`for the portion shown in Fig. '10, theprojections on the frame 97 forming a vertical bearing inside the curvedportion-ott fthe kribs 87.v The body bolster '98 -fot ithe 'locomotiveIbody 99 Lis =con nect'ed viin a usual vway with the 'truck (boilll l()ster 92. It will be noted that the frame mechanism for harnessing thetruck :trames into pairs and the trame mechanism for harnessing thepairs ot' trucks together both lie in approximately the same horizontalplane so the weight of the locomotive can be low on the track, a veryimportant consideration in locomotives tor high speed on sharp curves.

It is intended, owing to the novel insulating features otthe motors,that this locomotive will employ direct electric current of higherinitial voltage than is now the practice. The present initial voltage oldirect current adopted by the General Electric Company and thell'vestinghouse Electric and Manufacturing Company is three thousandvolts. I intend to employ six thousand volts pressure in the t\ventylourmotors ot the locomotive shown in Figs. (i and T. The dotted linesindicating electrical connections ot the motors illustrate thearrangement. The motors are divided into three groups ot eight motorseach. The motors ot each group are connected permanently in series withswitch connections between the groups so the three groups may beoperated in series or in parallel. The grouping of eight motors inseries reduces the voltage in the windings ot' any one motor to sevenhundred and liity volts, but the six thousand volt pressure remainsacross the line.
